Guide them by edicts, keep them in line with punishments, and the common people will stay out of trouble but will have no sense of shame. Guide them by virtue, keep them in line with the rites, and they will, besides having a sense of shame, reform themselves.
There is nothing divine about morality; it is a purely human affair. If people are good only because they fear punishment, and hope for reward, then we are a sorry lot indeed. What the individual can do is to give a fine example, and to have the courage to uphold ethical values .. in a society of cynics.
Capital punishment kills immediately, whereas lifetime imprisonment does so slowly. Which executioner is more humane? The one who kills you in a few minutes, or the one who wrests your life from you in the course of many years?
The contagion of crime is like that of the plague. Criminals collected together corrupt each other. They are worse than ever when, at the termination of their punishment, they return to society.
If soldiers are punished before they have grown attached to you, they will not prove submissive; and, unless submissive, then will be practically useless. If, when the soldiers have become attached to you, punishments are not enforced, they will still be unless.
Guide the people by law, subdue them by punishment; they may shun crime, but will be void of shame. Guide them by example, subdue them by courtesy; they will learn shame, and come to be good.
